Question

Esta frase es gramáticamente correcta:
Él estudió cuando yo entraba.
Answer True
False

Answer 1

i think is false but just check wth someone else ;)

Answer 2

The first verb is preterite which denotes a finite start and finish (in general) and the second is imperfect, which does not always have a finite start and finish. It reads something like this: He studied when I came over (to his desk, house, etc...)
Now you decide if it's right.
